Instead of getting customary dancing veils as expected, Oola was given only a flimsy net costume and a chain. But the way she danced while whipping her leash around, I figured out she was actually using it as a dancing veil.

Not to be a mensch or anything, but...If you have the video tape version of ROTJ and advance frame-by-frame thru the point where Jabba springs the trap door on her you can see her boobs pop out of her costume as she is falling.Enjoy!!!
